Step 1
Sampling distributions : The probability distribution of a given statistic based on a random sample.
The sampling distribution depends on: the underlying distribution of the population, the statistic being consider.
Let x1,x2,....xn are random sample from population with mean µ and standard deviation σ then sampling distribution of sample follows approximately normal distribution as,
xN(μx,σx) where σx=σn
And if population standard deviation \sigma is unknown then,
xN(μx,Sx) where Sx=Sn
Step 2
This distribution is normal since the underlying population is normal, although sampling distributions may also often be close to normal even when the population distribution is not.

(Select all that apply. To be marked correct: All of the correct selections must be made, with no incorrect selections.)
Question 3 options:
Its name is often abbreviated by the three capital letters CLT.
The accuracy of the approximation it provides, improves as the sample size n increases.
The word Central within its name, is meant to signify its role of central importance in the mathematics of probability and statistics.
It is a special example of the particular type of theorems in mathematics, which are called Limit Theorems.
It specifies the specific standard deviation of the curve which approximates certain sampling distributions.
The accuracy of the approximation it provides, improves when the trial success proportion p is closer to 50%.
It specifies the specific shape of the curve which approximates certain sampling distributions.
It specifies the specific mean of the curve which approximates certain sampling distributions.
